Wanted to let you guys know we are very close. I have moved all my efforts to thread located here: http://www.freaktab.com/showthread.php?93-Cracking-this-ROM-for-the-P700

We have our own section there, so I recommend everyone go there for this tablet

Glad bob was able to help!
[Android Q&A, Help & Troubleshooting] chidave09:
Bob helped in an unbelievable way! And now our problems are officially solved!!!!!

Go HERE to get his Rom

His rom is built from the original 2.4 update that was linked earlier in this thread.

- The original cramfs image has been converted to ext3

- All files edited to allow /system to be recognized as ext3

- Full root access with /system already mounted as R/W to allow writing

- You can use a root explorer to change this to R/O when R/W not needed

- Extra space added to system partition to allow files to be saved

- Custom boot image

Go download and make sure to read the thread and the readme file in the download before flashing anything! As always, NO ONE BUT YOU are responsible for any ill effects of any kind!!
[Android Q&A, Help & Troubleshooting] finlessbob:
Thanks Chidave for the props....

You guys waiting a long time for a full root...... ENJOY the ROM!

If it was not for Dave's help, it would not have happened. Thanks Dave.

Next.... Well...... lets make it even better...

Flashed the ptab7200 no problems... Working good... I want to customize this, i.e. custom notification stuff (systemUI.apk). I can do the mods but was wondering, since we have no recovery and cant flash zips, you think metamorph, zipthemer, etc would work? Dave hit me up on gtalk if this interests you...
[Android Q&A, Help & Troubleshooting] dennyik74:
Ok so this Rom is running great for me except I notice a few guys have the gapps loaded I can't get this to work for the life in me if anyone could help would be great so far I've tried renaming it to a apk no luck just don't understand beside install zip from SD in recovery how to do it thanx
[Android Q&A, Help & Troubleshooting] chidave09:
I was just starting to wonder about this to, but I seriously have no experience with this kind of stuff. I do plan on installing and attempting though!

Another thing I would like to fix is if you adb install -s, the apps seem to get installed on internal sd, not external. Also I would like to change default browser download location to external also. I know you can use a different browser and select your dl location, but for some odd reason I am kind of fond of the stock one
[Android Q&A, Help & Troubleshooting] drob311:
Which makes me think... I have 4GB flash memory aka internal sdcard... Is there anyway we could somehow install ubuntu from the flash aka internal sdcard? Now that we have root I think it will be possible... I'm gonna check into this more...

needing pointers

I am trying to flash this rom but i am not having alot success with it. I read everything but i seem to be unable to get in to the recovery. The drivers aren't working right. I have the ptab7200 and i am a noob to droid platform.
[Android Q&A, Help & Troubleshooting] x51:
I'm wondering what instructions you were reading. Flashing this rom shouldn't have anything to do with recovery. ;)

The drivers were very difficult for me as well...

First Make sure the tablet is in debug mode (settings > Applications > Development > usb Debugging) I think that bit is missing from the instructions.

Then plug it in and tell me what you see in Device manager.
[Android Q&A, Help & Troubleshooting] chidave09:
You should not have to have usb debugging turned on as the Android OS itself is not booting up when in this mode. I have some easier to read directions on installing the drivers and using the tool I posted way earlier in this thread, located HERE. If this still doesn't help, let me know.
[Android Q&A, Help & Troubleshooting] xigil:

Has anyone tried connecting to adb on OSX?

I'm using the standard adb I've used on my g1, pandigital novel, sidekick 4g, etc and it's not working right.

I can mount the ptab7200 via usb, read, write, without issue.

I can see the device via adb devices.

I can make it reboot via adb reboot. I can get the shell via adb shell.

Yet anytime I try to run a command, it seems the device disappears in adb. No errors, nothing returns. Adb devices at that point shows no devices.

Nothing in both the osx and the ptab7200's logs show a crash.

Do get this when connecting the usb cable.

Sun Mar 25 05:34:27 LAPTOPNAME kernel[0] <Debug>: USBF:\t697756.146\tEndpoint 0x83 of the USB device "PTAB7200" at location 0xfa134000: converting Bulk MPS from 64 to 512 (USB 2.0 Spec section 5.8.3)

Have tried reseting the device, and even flashing the 2.4 update from the southerntelecom/polaroid support page. No different.

Weird part, since the connection stays up as long as nothing needs to be returned. As per http://stackoverflow.com/questions/2604727/how-can-i-connect-to-android-with-adb-over-tcp

Once connected by usb, ran adb tcpip (portnumber)

then adb connect (portnumber)

and it worked. Connected, was able to run logcat and all.

Anyone else have the same issue? The connection just dies when trying to do anything on adb over usb.

I bought it from BigLots for 99 dlls.. it is a POLAROID PMID701C 4GB Internal memory.. im not sure about the chip if its a rockchip or not or wtf to be honest i dont have the market like most of this tablets i guess so maybe im messing arround with the wrong drivers but not sure please help me a little bit i tried the drivers from this post also the ones from freaktab and 3 different computers to be sure that it was not the cumputer. im runnin windows XP sp3 thanks in advanced
[Android Q&A, Help & Troubleshooting] chaostic_2k1:
The instructions with the finless roms arn't complete. The tablet should be off. You need to hold the menu button while plugging it into the usb. Then you can install the rockchip usb drivers.

If it gives you an error saying the device can't restart, just unplug the cable, and hold menu before plugging it back in.

OK...

I am now completely confused...

I have a 7200 that is completely charged that I can't get into due to some password issues (no...its just not taking my password ... I DO know what it is!)

I want to "factory refresh" it then root it yet the instructions here are not linear enough for me to understand.

I want to know what names you call each of the buttons:

at the bottom there is a back button a "center button" (home?) and a right button. Is this what you mean by "menu" button in all these instructions?

At the top is one button: what are you calling this button?

I want to reinstall the factory ROM first and go from there so any help would be appreciated.

[Android Q&A, Help & Troubleshooting] lieutenantsword:
I just picked up the PMID702C from Big Lots for $89.99. This is my official "review" of it, having had it now for about three hours:

I was pleased to see that the battery was fully charged out of the box. The tablet itself is light, but doesn't necessarily feel cheap or flimsy. It has a rear-facing camera that seems to take fairly decent photos, but no front-facing camera, flash or any of the other photographic accoutrements.

The tablet comes pre-loaded with Android 4.0.3, and I was pleasantly surprised to see it was pre-rooted! None of the GAPPS were loaded, but after a short search, they were easy to find and load. The Play Store crashed when I tried to download and run an unsigned version, but the signed version loaded fine and is running great. The tablet is now in sync with my account on Play, and will now take applications sent through the account.

I installed the Nova Launcher with no problems, and it's smooth and fast (as you'd expect). The layout is completely able to be customized, and with the new launchers in place (I also installed Apex), the design possibilities are limitless.

It's not a 3G/4G capable tablet, but locks up on WiFi just fine. It also has a AM/FM radio app that works great -- I locked up to my local stations without so much as having to configure my location. Good addition, in my opinion!

Oh, another very important and surprising thing I discovered was that even though this tablet comes with very little bloat, they're all able to be uninstalled, so you can literally begin with a completely clean tablet and make it your own.

If I were giving this tablet a 0-5 star rating, I'd have to give it a solid * * * *. If it had a front-facing camera with a flash, I'd have easily gone 5-stars for it. I hope someone has found this "review" helpful.

So can anyone give me a simple guide to root the PTAB7200?
[Android Q&A, Help & Troubleshooting] retrend:
I have just bought a Polaroid 40140, apparently it's an a13 allwinner at 1.2ghz with 512ram and 2gb storage. Comes with 4.0.4 on. Also is preloaded with play store working which seems to have been a major issue on other polaroids.

My first experience with a 7" tab, much prefer the size to a 10", not too happy with the performance though but it seems I'm going to have to put up with it because there's no one modding it etc as far as I can see. Only paid £70 for it and it was money I'd had refunded on groupon about 18 months ago but they just sell such junk I hadn't managed to find anything to spend the money on lol.

[edit] just installed nova instead of apex and cranked the animation speeds to "ignore animations make it fast" and now its performance seems a lot more reasonable

create image or update zip form files

Hellos i have Polaroid MIDC010 European version and i dont have the original firmware. so i start searching for a compatible firmware to restore it back to live. after several days i fund this site http://www.mms-support.net/ the official support site for polaroid (i am still waiting for them to reply me about the firmware).

Anyway, they have a firmware for a tablet very similar to what i have and i want to try that, but what they provide is a zip file that looks like to be inserted into a SD but i tryed that and it dont do anything. i wish to know is there is way to create from those files the update.zip or a .img file to flash the tablet.

this is the tablet similar to mine: MIDC497PR001

http://www.mms-support.net/index.ph...id=78&option=com_virtuemart&Itemid=15&lang=en

I just tried to install play store on a Polaroid MIDC407PR011, the result is that does not work and now i can't enable my wifi. The switch button stay off. Well i decided to do a recovery. Everything has been deleted but the wifi problem is still here.

Do you have any idea about this problem ?

[Android Q&A, Help & Troubleshooting] drob311:
Bucky! Anyhow... I cannot get the tab into recovery... I have seen the recovery. I did a factory reset from the settings and it kicked the tablet into recovery. I have a PTAB7200...
[Android Q&A, Help & Troubleshooting] chidave09:
I know there has to be one, I just got to figure out what the command is that tells it to do so. I tried the following from adb, am I missing anything?

adb reboot recovery

adb reboot bootloader

adb reboot-bootloader

They all just make the phone reboot normally like the reset button. Also tried every single button combo, but as I am sure you already know, it won't turn on when any other button is pushed. Why in the world would they do such a thing? Is it an effort to fight us or to make it even more idiot proof?
[Android Q&A, Help & Troubleshooting] drob311:
I believe the adb commands reboot recovery and bootloader don't work because of fastboot issues... my model doesn't have a battery that I can "pull", I took the tab apart and the battery is hard wired in... I'm guessing that's what the "reset" button on back is for... I got the update.img to unpack, now I got my ubuntu 11.10 fired up and I'm gonna try to get the unpacked images unpacked... ill keep the thread updated...
[Android Q&A, Help & Troubleshooting] rozzops:
So i moved the update.img to my linux box and tried to mount it but i get:

rozzo@ubuntu:~/Documents/rooting$ sudo mount -t cramfs -o loop update.img update
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

So i moved on and assumed it was encrypted so i tried to run rkDecrypt on the file and I got:

C:\rooting\pmid700\sandbox>rkDecrypt system.img
warning: file not crypted

So a little weird. I tried to see what type of file this is:

rozzo@ubuntu:~/Documents/rooting$ dd if=update.img | file -
[B]/dev/stdin: data[/B]

and Then the cool part (looks like the root directory structure):

rozzo@ubuntu:~/Documents/rooting$ dd if=update.img | strings | head -20

I haven't gotten too far tonight on this and wont be able to try this again until tomorrow but it appears this is some weird type of cramfs which its just raw data with a .img extention (maybe I'm wrong). On the positive side we now have the image extracted and can see whats in the file but still cant mount it.

I haven't given it much thought how to get into recovery mode. I have the pmid700 (menards) so any help figuring that out would be awesome.
[Android Q&A, Help & Troubleshooting] chidave09:
Awesome, this is probably nothing but I figured I would post it anyways. I was just messing around and tried to unyaff the .imgs I got off the other partitions.

Correct me if I am wrong but wouldn't we be able to easily make a new system.img once we figure out how to flash anything? As in I just did a tiny bit of research on cramfs and it seems pretty simple. Here is a whole tutorial on building one and adding it into the kernel, good read.

since you created directory tmp you should try to mount to that directory so do this:

that should mount it to that location. However i think it will error saying it needs a mount type (-t cramfs). This is where i got to last night where it wont let me mount this image since its not normal type of cramfs.

this sounds promising: http://www.slatedroid.com/topic/19808-rk29xx-imagetools-v21/page__view__findpost__p__271348
